To all whom it may concern."

lie it known that I, SILAS M. FORD, a citizen of the United States, and a resident cit" tit. Paul, in the county of Ramsey and State of lllinnesota, have invented certain new and useful Improvements in Machines tor ll iaking hath-Board, of which the following is a specification.

This invention. relates particularly to a machine for making lath-hoard wherein the latlrboard, preferably of Water-prooted lihrous material, is crimped into a corrugated or dove-tailed shape, and is a divisional of my co-pending application, Serial #96259, filed May 8th 1916 and hearing the same title.

One object of my invention is to provide in a machine for crimping material into a corrugated or dove-tailed shape, means for pressing the material so formed firmly and positively into its permanent shape and maintain it in such shape as it progresses through the machine.

Another object of my invention is to provide in a machine for crimping lath board into a corrugated or dove-tailed shape, rotative means for pressing the corrugations termed into their permanent shape during the progress of the material through the machine.

Another object of my invention is to pro vide in a machine for crimping lath-board into a dovetailed or corrugated shape rotative means for striking similar edges of the corrugations and force them into their permanent position.

With these and incidental objects in view, the invention consists of certain novel features oi construction and combination oi. parts, the essential elements of which are hereinafter described with reference to the drawings which accompany and form a part ct this specification.

Figure l is a side elevation of a portion ot' a machine for making lath board embodying my invention, and Fig. 2 is a plan view at a part of the machine with the paper and all mechanism above it removed to show the lower series of slats.

Fig. 3 is a side elevation of my improved means for forcing the rectangular corrugated paper into a dove tailed formation; and a is a plan view of the same.

5 is a side elevation of an alternate construction of the forcing means shown in Fig. 2;and Fig. 6 is a plan view 01": the same,

A sheet of suitable material 1, Fig. 1, is taken from the roll E2 and passed through a pair of corrugating rolls 5 and 6, similar to those described in my application aforesaid, and the paper is thus formed into rectangular corrugations as at a, as described in said application.

Driven by the rolls 5 and 6, by any suitable set of gears, are a pair of shafts 51 and 52, Fig. 3, carl' ying slats 53 and 5-1 respectively, the gear ratio being such that the slats or will strike points 55 of the corrugated paper, and the slats 53 will strike the points 56 oiithe corrugated paper, there by forcing the corrugated shape into a dovetailed shape asshown at 57.

A modification for attaining the same end is shown in l and 5, in which the slats 51 and 52, Figs. 2 and 3, are replaced by slats 56 and 59, and 65 and 66, Figs. 4 and 5.

A shaft 60, Fig. l, has keyed thereto a series of sleeves, each carrying the sectional slats 58. .l'ournaled on the shaft 60, a series of sleeves 61 carry slats 59, and these sleeves are driven by gears 62 integral with the sleeves 61, by pinions 63, driven in turn by the chain of gears 6%.

The lower shaft also carries a similar set of keyed and iournaled sleeves, which carry slats and 66, similar to slats 58 and 59, respectively.

It is evident that with the series of slats 58 and 65 driven in an anti-clockwise direction, while the series of slats 59 and 66 are driven in a clockwise direction, and the gearing oi the shafts 60 and 60, and the rolls 5 and 6 of the pro oer ratio, the slats 58 will strike points 67, slats 59 traveling in a clockwise direction will strike points 68, While slats 65 traveling in an anti-clockwise direction will strike points 69, and slats 66 traveling in a clockwise direction will strike points 70 off the corrugated paper, thus terming it from a corrugated shape, shown at 71, to the dove-tailed shape, shown at 72.

While I have described my invention and illustrated it in one particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the application of my invention-may be varied in many Ways Within the scope of the'following claims: 7

1. In a machine for making lath-board, the combination of a pair-of'eorrugating rolls, a pair of shafts having forming slats thereon associated With said rollsa-nd adaptedto strike. the material, after it has left the corrugating rolls in a corrugated form, and force the material into a dove-tailed plaited form. r e

2. In a machine for making lath-board, the combinationzof a pair of corrugating rolls, a pair of shafts having forming slats thereon, 'a stripper guide for guiding said material from said corrugating rolls through said pair of shafts, timing means connecting said eorrugating rolls'and said shafts so that said forming slats Will strike the faces of'said corrugated sheet and force the sheet into a dove-tailed plaited formation;

3, In. a machine, for making lath-hoard the combinationof a pair of corrugating rolls; a pair of shafts having formingslats thereon, a stripper guide for guiding said material from-said corrugatin'grolls through said pair of shafts, timing means connecting said :corrugating rolls and said-shafts so that said forming slats will strike the faces of said corrugated sheet and force the sheet into a dove-tailed plaited formation, said stripper guide being narrowed where it passes through said forming slats.

4. In a machine for making lath board, the combination of a pair of corrugating rolls, a pair of shafts having forming slats thereon, there being a series of grooves in said forming rolls and said forming slats, a series of stripper guides associated with the lower of said corrugating rolls and slats in said grooves, a second series of guides asso ciated with the upper of said curl-ligating rolls and said forming slats, in said grooves, the distance between said two series of guides being less where they pass through said slats having forming means thereon, than where they pass through said corrugating rolls.

5. In a machine for making lath-board, the combination of a pair of corrugating rolls, a series of forming slats rotatable in one direction, and a second series of forming slats alternatel; positioned with said first series, rotatable in the Opposite direetion for forming material, as delivered in a corrugated shape from said corrugating rolls, into a dove-tailed shape.
